You should let your lawyer handle getting a copy of the video. They always give citizens, and especially accused people, the runaround.
Time to talk with a local attorney.

If a trooper investigated the accident, you should be able to obtain the full accident investigation report from the Texas Department of Public Safety. The trooper likely obtained a copy of the video from NTTA and it should be in the investigation file. If you try to get it from NTTA, you will probably continue to get the "runaround" about how you can actually obtain the video. Here is the link to the public information request on the DPS' website:
Hope this helps--good luck!

In these situations you can not do an Open Records Request because the state will see it as an attempt to bypass the discovery process of the criminal courts. If you've been charged with a crime, you'll have to wait and get the video from the DAs office.
If it is for a civil suit too, the video will not be released by DPS until the criminal matter is concluded. Hire an attorney on your criminal case and they will be able to view the video. Good luck and feel free to contact me to discuss your options.
